Check out last year's telling of Vayishlach.

Before Yakov re-encounters Esav he is confronted by a mysterious being that ends up having the divine power to bless him with a new name - Yisrael. A Midrash suggests that this encounter was an epic cosmic battle between the mortal Yakov and Esav's arch-angel that elevates Yakov to a super-natural being. Yes, this is Torah not Harry Potter.
